Technical note

Before you convert HFZ to TIF

Every cell in an HFZ file holds a measurement rather than a colour, usually elevation in metres, running from sea level up to whatever the highest point in the tile happens to be. TIF stores brightness, so the conversion stretches that range across a grey or colour scale. What you get is a readable picture of the terrain, and it is the right thing for a relief map or a figure. What you no longer have is the data: sampling a pixel in the TIF returns a shade, not an altitude. Missing cells in an elevation grid, such as water, radar shadow or the edge of a survey, are not empty: they hold a sentinel value, -32768 in SRTM, -32767 in DTED and very often -9999 in ESRI grids. Counted as a real height, that value stretches the scale so far that the actual terrain collapses into a few near-identical shades. When a TIF output looks flat and washed out, a void treated as data is the usual cause.

Map Data Workflow

Turn GIS data into something anyone can open

Not everyone who needs to see HFZ data has GIS software. reaConverter renders it to TIF for a report, an email or a slide, and handles a whole folder in one run.

  • Render every file in a folder to TIF with the same size and settings
  • Set DPI and output dimensions before the run, not afterwards
  • Stamp a text watermark, such as a project name or a date, on every image
  • Pick up new data automatically with Watch Folders, or script the job from the command line

Everything runs on your PC, which matters for cadastral, utility and client data that should not pass through an upload form.

I firmly believe working with JPEG — the universal format supported by all devices and apps—is the wisest choice. reaConverter handles these conversions flawlessly.

FAQ

HFZ to TIF Conversion

What are HFZ files?

HFZ is the compressed version of the HF2 terrain height map format, in which the whole file is packed with the gzip method. A height map is a rectangular grid where every cell holds the elevation of one spot of a landscape, and such grids can grow very large when they cover wide areas in fine detail. HFZ keeps them small by combining two ideas: heights are stored as differences between neighboring cells, and the author chooses how precise the heights need to be. The same data can also be found with the .hf2.gz extension. In a published comparison, a terrain saved as HFZ took about 1.4 MB, while the same terrain in the TER format packed with gzip took 1.8 MB, at equal vertical precision.

What are TIF files?

TIF (Tagged Image File) is a popular type of raster graphic file, suitable both for handling with various types of image editing software and with scanning or printing equipment. Since the 1980s when it was created, the TIF format has received a series of improvements, so at the moment there are several types of the TIFs available. Some of the main advantages of using TIF files include flexibility and high image quality.
